Revisions to Safety Standard for Portable Hook-On Chairs

In March 2016, the U.S. Consumer Product Safety Commission (CPSC) published a consumer product safety standard for portable hook- on chairs based on the ASTM voluntary standard for portable hook-on chairs. ASTM has since published a revised voluntary standard for portable hook-on chairs. We are publishing this direct final rule, revising the CPSC's mandatory standard for portable hook-on chairs to incorporate by reference the more recent version of the applicable ASTM standard.
